I forgot to ask you, what are you using for your tenant networks?
VLANs, flat, GRE or VXLAN?

You'd only have to change the Packstack answer file. You should run
packstack --gen-answer-file=ans
'ans' will contain an answer file with all-in-one default values.
You should add all of the compute nodes to the compute node list
(Providing their management IP). If you're using VLANs then fill
in the bridge mappings keys (You'll put in the second NIC there),
or if you're using tunnels then specify the 2nd NIC as the tunnel
endpoint. The RDO docs have more specifics.
